The patch titled
imm: no need for unchecked_isa_dma
has been removed from the -mm tree. Its filename is
imm-no-need-for-unchecked_isa_dma.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.
------------------------------------------------------
Subject: imm: no need for unchecked_isa_dma
From: Randy Dunlap <rdunlap@xxxxxxxxxxxx>
Relax the lowmem bounce buffer requirement for imm so that any low memory
page will do -- they don't need to be below the ISA 16 MB limit, just need
to be mapped in low memory.
